Business Functions, Processes,
and Data Requirements

Concepts in Enterprise Resource Planning, Second Edition 2
Chapter Objectives
• Name a business's main areas of operation.
• Differentiate a business process from a business
function.
• Identify the kinds of data that each main functional area
produces.
• Identify the kinds of data that each main functional area
needs.
• Define integrated information systems and state why
they are important

ERP Overview
• Enterprise Resource Planning (ERP) programs are
software used by companies to manage information in
every area of the business.
• ERP programs help manage company-wide business
processes using a common database and shared
management reporting tools.
• ERP software supports the efficient operation of
business processes by integrating activities throughout a
business.

Functional Areas of Operation
• Most companies have four main functional areas:
• Marketing and Sales (M/S)
• Supply Chain Management (SCM)
• Accounting and Finance (A/F)
• Human Resources (HR)
• Each main functional area consists of a number of
narrower business functions specific to the functional
area.
• Historically, businesses have organized themselves
according to business functions.
• Business Schools continue to be similarly organized.

Functional Areas of Operation

Information System
• An information system includes the:
• Computers
• People
• Procedures
• Software
• Required to store, organize and deliver information
• Information systems are a critical tool for integrating
business functions

Business Processes
• A business process is a collection of activities that takes
one or more inputs and creates an output that is of value
to the customer
• The customer may be the traditional external customer
who buys the product or service, or an internal customer
(a colleague in another department)
• The business process view is the customer’s
perspective.
• The customer does not care that different functions are
involved in processing their order, and will not tolerate
mistakes and delays caused by poor coordination of
business functions

Integration of Business Functions
• Sharing data efficiently and effectively within and
between functional areas leads to more efficient
business processes
• Information systems that share data between functional
areas are called Integrated Information Systems

Another Look—Nova Chemicals
• According to John Wheeler, CIO of Nova Chemicals,
changing from a function-oriented view to a process-
oriented is a complicated process
• Business processes include:
• People with particular skill sets
• Information
• Tools
• Correct organizational culture

Another Look—Nova Chemicals
• Nova has identified 3 core processes:
• Demand Chain Management
• Supply Chain Management
• Manufacturing Management
• And three enabling business processes
• Human Resources (includes corporate
communications)
• Treasury
• Information Technology
• Process Boards consisting of managers from various
functional areas define “best practices” and process
metrics—clear measurements to manage business
processes

products, takes customer orders, and creates sales
forecasts.
• Supply Chain Management: Develops production
plans, orders raw materials from suppliers, receives
the raw material into the facility, manufactures
products, and ships products to customers.

Summary

of:
• Accounting and Finance: Records sales transactions,
records customers’ payments, records suppliers’
invoices and payments to suppliers, and summarizes
operational data in managerial reports.
• Human Resources: Recruits, trains, compensates,
and oversees the evaluation of employees.

Summary
• Functional areas are served by information systems,
which capture, process, and store data to provide
information needed for decision making.

Summary
• Employees working in one functional area need data
from other functional areas. Functional area information
systems should be integrated, so shared data are
accurate and readily available.

Summary
• Business managers are increasingly thinking in terms of
business processes that integrate functional areas.
• The business process view promotes efficiency and
competitiveness.
